What is the intArrayOf() method in Kotlin?
Overview
The intArrayOf() function in Kotlin creates a new array that can hold integer elements.
By providing the integer values as arguments, we can also pass the elements to be included in the array.
Syntax
fun intArrayOf(vararg elements: Int): IntArray
Parameter
This method takes the integer elements to be included in the array as an argument. The argument is of a variable type. So, we can pass any number of integer elements.
Return value
The intArrayOf() function in Kotlin returns a new IntArray containing the provided integer numbers that are passed as arguments.
Code
The code below demonstrates how to use the intArrayOf() method in Kotlin:
fun main() {val intArray = intArrayOf(1,2,3,4,5);print("intArray is: ");println(intArray.joinToString(" "));val emptyIntArray = intArrayOf();print("emptyIntArray is: ");println(emptyIntArray.joinToString(" "));}
Explanation
-
Line 2: We use the
intArrayOf()method with1,2,3,4, and5as arguments. This method returns a newIntArraywith1,2,3,4, and5as the elements of the array. -
Line 4: We use the
joinToString()method to convert the array into a string. Then, we print it. -
Line 6: We use the
intArrayOf()method with no arguments. This method returns a new emptyIntArray.
